Well, there's definitely a difference of some sort. I'm in the process of putting a 1955 235 C.I. 6 cyl. truck engine (dated Feb 6, 1955) in a friend's truck. The old engine was was a 1955 passenger car engine dated June 14, 1955. It has hydraulic lifters, the truck engine has solids.
The truck engine must have a bigger harmonic balancer, because I had to get a fan belt 2" longer than what was used. This is with the old water pump and alternator being used on the replacement engine.
They use different dipsticks too, by the way.
